The aim of the study was to determine the type, intensity and duration of post operative sensitivity (POS) in class I and II cavity restorations with self-etching adhesive and nanofilled composite.
The clinical study included 34 patients, who received a total of 76 restorations by undergraduate dental students. The restorations were made in medium and deep cavities. Self-etching adhesive Adper Promp L-Pop and nanocomposite Filtek Supreme (3MESPE Dental products USA) were placed. The type, the magnitude and the duration of postoperative sensitivity were examined on days 1, 3, 5, 7, 14 and 30. Intensity of sensitivity perceptions were recorded on a visual analogue scale using the method of self-observation. Parametric and non-parametric analyses were employed at a significance level of P < 0.05.
Pressure-dependent POS was present in most of the cases (15.78% +/- 4.209), followed by discomfort (9.21% +/- 3.340) and pressure- and cold-induced pain (1.33% +/- 1.147). A statistically significant difference was found between days 1 and 3, and between days 5 and 30, as well as between days 7 and 30 (Wilcoxon Signed Ranks Test, P < 0.05). Rapidly disappearing POS (within 1 week) had the highest percentage: 75% +/- 9.934.
Following restoration of class I and II cavities with self-etching adhesive and nanofilled composite POS was established in 26.3% of the cases.
本研究旨在确定使用自酸蚀粘结剂和纳米复合树脂修复Ⅰ类和Ⅱ类洞形后，术后敏感（POS）的类型、强度和持续时间。
本临床研究纳入34例患者，由牙科专业本科生为其共进行76颗牙齿的修复。修复均在中、深龋洞中进行，使用自酸蚀粘结剂Adper Promp L-Pop和纳米复合树脂Filtek Supreme（美国3MESPE牙科产品）。于术后第1、3、5、7、14和30天检查术后敏感的类型、程度和持续时间。采用自我观察法，通过视觉模拟评分记录敏感程度。采用参数分析和非参数分析，显著性水平设定为P < 0.05。
大多数病例中存在压力依赖性术后敏感（15.78% +/- 4.209），其次是不适（9.21% +/- 3.340）和压力及冷刺激诱发的疼痛（1.33% +/- 1.147）。在第1天和第3天之间、第5天和第30天之间以及第7天和第30天之间发现有统计学显著差异（Wilcoxon符号秩检验，P < 0.05）。术后敏感迅速消失（1周内）的比例最高：75% +/- 9.934。
使用自酸蚀粘结剂和纳米复合树脂修复Ⅰ类和Ⅱ类洞形后，26.3%的病例出现术后敏感。
